Subject:

Interim 10CFR50.55(e) Report: Control Rod Drive Mechanism, Heavy Drive Screw, Breech Guide Screw

Dear Sir:

In Reference (c) we reported a potential 10CFR50.55(e) item associated with the breech guide screw on Control Rod Drive Mechanisms (CRDMs) with the heavy drive screw. Field inspection of our CRDMs indicates a potential for the problem described by Westinghouse in Reference (b). Based on this inspection, this item is reportable under the provisions of 10CFR50.55(e).

We are currently working with Westinghouse to develop corrective action to prevent the possibility of loose and dislodged breech guide screws in our CRDMs. We will submit an additional report regarding this matter.

This report is submitted in accordance with the interim reporting provisions of 10CFR50.55(e)(3).

Very truly yours, t
